Inland Empire Paper Taps AlgEvolve for Biological Wastewater Plant

Inland Empire Paper Company and AlgEvolve Inc. have commissioned an advanced biological water treatment system at the IEP facility located in Millwood, Washington.

Montana-based AlgEvolve developed its Advanced Biological Nutrient Recovery system to remove phosphorus, nitrogen, and other constituents without the use of strong chemicals, relying instead on a carbon sequestration process that produces oxygen and algae byproducts, the company says.

AlgEvole’s system was chosen out of 10 different systems, primarily because it eliminates the use of chemicals and the disposal challenges of chemical sludge.

The system uses the production of algae to consume nutrients in a water stream. Through this process three valuable products are produced: clean water suitable for reuse; pure oxygen; and a potentially valuable algae biomass which has demonstrated uses for a number of applications including bio-plastics, fuel and agricultural feed ingredients.

According to Mike McGowan, vice president of technology at AlgEvolve, the algae that the system uses is naturally occurrent in every existing wastewater facility. This system simply harnesses the organism’s natural ability to soak up surplus nutrients. He describes the process as “mimicking nature.” In addition to recovering nutrients from the water, the production of algae also consumes carbon dioxide and releases oxygen.

Earlier this month Ford Motor Company of Southern Africa announced plans to invest about $2.5 million in a new wastewater treatment plant from Veolia Water Solutions & Technologies South Africa, to facilitate the manufacturing of the all-new Ranger at its Silverton assembly plant.

The Veolia subsidiary will design, supply and install the treatment plant that will also see the first locally installed ContiFilt, a technology of continuously regenerated sand filtration.

The existing decade-old wastewater treatment plant that previously pretreated water before it ended up at the Tshwane Sewage Works is no longer able to handle the new capacity and municipal requirements, Ford said.
